So i have a note 3 i recently bought into and am wondering whats up with the wireless charging? From what i've read it is supposed to be Qi, but its not built in? I mean i paid retail for this thing nearly 800 bucks and i have to buy into it more? If i could i'd like to confirm that i can use any random ebay qi charging pad when using the right Note 3 Charging cover?

Yes, it's not a much talked about feature, in fact I forget it was even possible. Qi charging pads are never included with phones, but as a consolation the pad will work with any future Qi compatible phone you buy. But the backs sometimes cost extra-- the idea is why raise the product cost further for folks who'll never use the wireless charging. Samsung's own S-View flip cover supports wireless charging: http://www.samsung.com/us/mobile/cell-phones-accessories/EF-TN900BBESTA . Any Qi compliant charging pad will work. The back cover you found should also work.
